Zusammenfassung: | The invention relates to an equipment for metal parts stress relieving by means of vibrations, intended to be employed to reduce internal stress generated within the structure of said parts during forging, casting, welding or machining, where the claimed equipment may be placed at a distance of up to 15 m from the metal part to be subjected to stress relieving, resulting in a high reliability of the electric motor. According to the invention, the equipment comprises an electric or pneumatic motor () of a power of 10 kW, at the most, and a rotation speed of up to 10000 rpm, which is able to remove stress at accelerations of more than 10...15 g and transmits the mechanical rotation power from the shaft of the electric or pneumatic motor () to a vibrator () with eccentric by means of a flexible shaft ().
Invenţia se referă la un echipament pentru detensionarea prin vibraţii a pieselor metalice, care se foloseşte la reducerea tensiunilor interne introduse în structura acestor piese în timpul operaţiilor de forjare, turnare, sudare sau de prelucrări mecanice, echipamentul putând fi amplasat la o distanţă de până la 15 m faţă de piesa metalică ce urmează a fi detensionată, ceea ce determină o fiabilitate ridicată a motorului electric. Echipamentul conform invenţiei este constituit dintr-un motor () electric sau pneumatic, cu puterea de maximum 10 kW şi turaţie de până la 10000 rot/min, care poate realiza detensionări la acceleraţii de peste 10...15 g, şi care transmite puterea mecanică de rotaţie de la axul motorului () electric sau pneumatic către un vibrator () cu excentric, prin intermediul unui arbore () flexibil. |
